I understand that it is possible to speed up surfing, especially using a
wireless Internet connection, by using DNS caching locally. This has to
do with enabling the named daemon or something, but I understand that
there are some restrictions.
Is there a simple recipe explaining how to do this?
The FreeBSD handbook has an example. Just skip anything about setting up
authoritive name servers.
That said, if all you need is caching (ie. you have upstream nameservers
you can use), I'd suggest dnrd. It's extremely easy to setup. It's in the
ports.

What DNRD is
Domain Name Relay Daemon is a caching, forwarding DNS proxy server. Most
useful on vpn or dialup firewalls but it is also a nice DNS cache for
minor networks and workstations.
Features
* Caching of DNS requests.
* Support for backup DNS servers.
* Uses random source port and random query ID's to prevent cache
poisoning.
* Support for simple routing - specify different forward DNS servers
for different domains.
* Force authorative or unauthorative answers for specified domains.
* Share the /etc/hosts over the network.
* Support for openbsd, freebsd and linux.
* TCP support
* DNS blacklist support
